PLATE TECTONICS CONCEPTS
Introduction
Plate tectonics- The idea that Earth’s surface is divided into large plates that move slowly and change in size over time.
This idea provides a model for understanding many geologic features: faults, folds, volcanoes, earthquakes, and mountain belts.
Plate Tectonics is the culmination of two pre-existing ideas:
1) Continental Drift- The idea that continents move freely over Earth’s surface, changing their position relative to each other. This concept was proposed by German meteorologist Alfred Wegener in the early 1900’s.
2) Seafloor Spreading- The concept that new seafloor forms at mid-ocean ridges, and then moves horizontally away from the ridge toward an ocean trench/subduction zone (the seafloor is a conveyor belt). This idea was proposed by Princeton geologist Harry Hess in 1962.
The Early Evidence for Continental Drift
1) The continents look like they could fit together (like a puzzle).

2) Rock types are correlated from continent to continent (across the oceans).
3) The extinct plant fossil, Glossopteris, which grew in temperate climates, is found in South America, Africa, India, Antarctica, and Australia.
4) The extinct reptile, Mesosaurus, is found only in Brazil and South Africa. The mesosaurus lived only in freshwater, and could not swim across oceans.
5) Ancient glacial deposits in South America, Africa, India, Antarctica, and Australia suggest these continents were all located near a polar region
